Search warrants were served Saturday morning to 16 Baltimore County flea market vendors believed to be selling counterfeit property.

Beginning at 10 a.m., detectives served a series of warrants at the Plaza Flea Market, in the 2400 block of Old North Point Boulevard in Dundalk.

The vendors allegedly sold merchandise featuring brand names such as Nike, Apple, North Face, Polo, Ugg, True Religion and Timberland to undercover detectives throughout the investigation.

In addition, detectives were able to purchase counterfeit movies and music from various stands, according to officials.

The raid was funded by a grant from the Federal Bureau of Justice Assistance Intellectual Property Theft Enforcement Program after authorities received several complaints about illicit property.

Detectives worked with trademark representatives for major brands for several months to gather evidence in connection with the investigation.

The representatives included the Recording Industry Association of America, the Motion Picture Association of America, Stumar Investigations and Walters Investigative Services.

While the search warrants were being served, detectives shut down the flea market to ensure that the vendors involved remained at the scene and that no evidence was removed prior to seizure by detectives.

The investigation into the vendors is ongoing. The seized merchandise will be evaluated by trademark experts, and charges are pending against vendors found to be selling counterfeit items.
